The 21st year: transcription, motif list, and relation score

This study collected fMRI data when 25 participants listened to a story ("The 21st year"). We implanted 28 recurrent narrative motifs in the story, which were expected to create connections between separate events that shared the same motifs. The participants’ understanding of the relations created by these motifs was assessed by 5 independent raters based on post-scan questionnaires. This dataset includes the transcription of the story, the list of motifs, the fMRI participants' responses to the relation test, and the relation scores. (averaged across raters).

A professional writer custom-designed a narrative with two independent storylines, interleaving across minute-long segments (ABAB). In the last (C) part, characters from the two storylines meet and their shared history is revealed. Part C is designed to induce the spontaneous recall of past events, upon the recurrence of narrative motifs from A/B, and to shed new light on them. Our fMRI results showed storyline-specific neural patterns, which were reinstated (i.e. became more active) during storyline transitions. This effect increased along the processing timescale hierarchy, peaking in the default mode network. Similarly, the neural reinstatement of motifs was found during part C. Furthermore, participants showing stronger motif reinstatement performed better in integrating A/B and C events, demonstrating the role of memory reactivation in information integration over intervening irrelevant events
